When I create a node like this:

$nodeSetup = [
  'nid' => NULL,
  'type' => $bundle,
  'uid' => $uid,
  'revision' => 0,
  'status' => 1,
  'body' => ['format' => 'full_html', 'value' => Xss::filter($body)],
$_node = Node::create($nodeSetup);

the body value and format work fine. But, when I load an existing node, how can I set the body value keeping the format? This didnt work:

$_node->body->format = 'full_html';
$_node->body->set('format', 'full_html');

The following worked for me,

$node = \Drupal::entityTypeManager()->getStorage('node')->load($nid);
$node->body->value = 'body';
$node->body->format = 'full_html';//omitting this will retain existing format
  • $node->body->format = 'full_html'; didnt work for me. But, when the node was created with that format in the first place, $node->body->value = 'body'; works. But using the ->set() function seems to overwrite the format setting. Very strange and 0 documented...

    @Alex, the answer seems OK to me, you can set properties of the field one at a time. set() is applied on the entity, not the field. If you want to set a field, use setValue() to set all properties at once and for this you provide an array (like you did already when creating the node).

Kstack's solution works. Another option is to supply the value and format together in an array like so:

$node = \Drupal::entityTypeManager()->getStorage('node')->load(1);
$node->body->setValue(['value' => 'body', 'format' => 'full_html']);
